 Hi, I'm Frank, actually I'm from the Huawei transmission part. So in this booth, we want to introduce you to this transmission network. 800 gigabit? Yeah, 800G, because you can see this transmission like the G-shape. Why we use this architecture? In the backbone part, right now the traffic is data-centric from the east to the west. And also from the north to south, we call it MetroWDM. This is a traditional traffic. So how to reach the biggest capacity and the biggest stretching longer distance? This is the key for the transmission backbone and for the Metro, we need to share in architectures. So in this type, I bring you these two architectures or two technologies to introduce the Huawei, the new technologies. Is this the fastest backbone technology in the world? Yeah, for example 400G and 800G. Right now we already reached the longest distance test in China, Chinese mobile. And also this is unique in the Huawei, we use the optic switch. You can see this one, it's like the A4 size. This is real? This is real, it's our equipment. It's printed electronics? Yeah, print the fiber cores. You print it? Yeah, printed. So compared with the backbone in the core side, traditionally you have so many fiber cores. But if we printed this one, we will save a lot of space in here. And also for the sharing architecture, it's the same. We can come to here to see. Traditionally, each wing, each WDM side, we have each wing, we have unified dedicated wing, dedicated side in here. And so, but for the last mile, the traffic has done so huge. Usually this have the 40 lambda system, 40 wavelength systems. But this one, only in the last mile, only a few wavelengths to use. That's why in the traditional way built WDM, they will waste a lot of pressures for the aggregation side. But for the new technologies, we use the, we call the Blade OXC Pro. This one is the pulling architecture. Use the same rings, but we only use the one rack, one car. So one car for light rings, right? One car. One car is this car. Actually, we have the rear car in here. Is this car? This car? Yeah. You can see this car, they have the light ports, each port supports each directions. So the sharing architecture, in this case, you are saving a lot of the resource in this aggregation layer. From the aggregation side, you only have a little one rack. So you save a lot of space here. And also, we have this automatic, you can see this is the key components. We call it 3D air course. Liquid crystal on silicone. You can see here, traditionally, you have only one inside and different outside with this one to reflect, right? To reflect, to adjust in different directions. But for this, we call it 3D. Different fields inside in here. So that's why we like different planes with different input and different output. So that only one by N is M by N. So this one is the new technologies to evolution. Based on this evolution, we can do the sharing architecture. Save a lot of the space, power consumption. For sure, the course also save me a lot. Same performance? Same performance. Same bandwidth? Same bandwidth. Liquid crystal. Liquid crystal. It's like LCD. It's similar. But the LCD, that one is for the display. This one is for different direction, to switching. Switch the direction? Switch the direction. And this is 100 to 400 G. This one is for this, we call this ring. In the beginning, you can see in here, we have the different traffic. From the 4G to 5G, we have 25G traffic in the access side, 60G in the Hong Kong band, and also for this enterprise, right? We have almost 100G. That's why in the day one or day zero, we have this 100G in the small board process. And in the next, for example, two or three years, we call the 400G evolution, right? 80% lower power consumption. Yeah. 90% lower footprint. Footprint, yeah. What's the footprint? Footprint right now is night traffic. For example, you have night traffic, light car. But right now, it's only one car. That's why we save the space. This is already deployed? Yeah. This is already deployed. We already released this product on this March, MWC Barcelona. So right now, we have these small applications, right? We have more than 15 commercial use and 30 POCs. And so this is... No, this is the backbone, from the backbone part. Yeah, backbone part. Before I introduced for this one is the front-sharing architecture is the metro. And this is a new way of doing things. This one is actually not a new way, but it's a unique way. Because this one we developed two years, three years ago. And we've deployed a lot of the seats on the world, okay? So what do we see here? This is the WSS. This is like used different... You have different location. You use this component to switch from direction A to direction B to direction C. With this component. It looks like a prison. Yeah, this one is... It's actually how you design it inside. This one, air course. So like you can see it's like this one. You have air course inside. You use the wattage control. Control this liquid crystal. And this liquid crystal like a mirror. Use different angle to do the optical switching. So this one is the C-band and the air-band. Right now the Huawei we unified the... You can see the traditional way C-band and air-band is different lengths to alignment. Right now we call the metamans. For these technologies you can see inside. We have different color. Use different face, right? So this one to totally replace the lens. With this one you can switch in with the more capacity. And the switching and those few components. Based on this one you can double capacity. No more lens. Right now it's not. Because the metamans we already filmed in this lens. Nice. That's why in this one we have the new technologies and we call the integrated WSS. Industry first. Yeah, this is integrated. And what do we see here? This one is for a different band. Transmission is very like the wireless. We have different spectrum. Spectrum and support of the capacity. For this one, for example, this one is the C-band and the air-band. C-band is the traditional band. So new one is the air-band. So Huawei doped the different materials inside this fiber. Urban doped the fiber. For this one we can enlarge the Nalbongni C-band also to the air-band. With this type of this we can double the fiber capacity. And this one is the module like the NG. We like 400G, 800G use this module to do transmission. Very long distance. We can reach the 6,000 kilometers in this moment. 6,000 kilometers? Yeah, without the generation, without the electrical generation with this one. That's crazy. That's it.
